Whilst interesting and it looks pretty good, there are a lot of ARM based systems either out already or hitting mass production soon that are equally... if not more tempting in terms of price.

For all the issues around it's weirdy beardy USB system (which a lot of people will never encounter) the Raspberry Pi costs £30ish; I've one sat here running XBMC and doing 720p (the Pi can do 1080p but my TV can't) h264 playback happily.

So why would I drop 500 notes on this thing instead of 400 on a Dell laptop that'd have a screen or 30 odd on a Pi if I wanted a frontend to play media?

The size is impressive, but the price puts it over the line. A local PC shop sells an everything-but-the-OS box the size a mini-desktop with a dual core 64bit Atom processor for $200. I added an Intel nic and made a router out of it.
